Definitions

  • the present invention refers to a process for the preparation of azole compounds endowed with antimycotic activity.
  • the compounds of formula I
  • Rj is chlorine, fluorine or trifluoromethyl
  • R 2 is hydrogen, chlorine, fluorine or trifluoromethyl
  • R 3 is C M alkyl
  • R-t is a C ⁇ _ 5 polyfluoroalkyl group containing at least two fluorine atoms and optionally other halogen atoms selected from chlorine and bromine; and their salts with pharmaceutically acceptable acids, are known as antimycotic and antifun- gal agents.
  • Rj and R 2 are as defined above, and R is hydrogen or a protecting group for the hy- droxy moiety.
  • This compound is described and claimed per se in the co-pending patent application filed in the same date of the present one by the Applicant. It is epoxidized, for example according to what described in the patent EP-0 046 033 (in the name of Standford University) which uses titanium alcoholate in the presence of a suitable derivative of tartaric acid and of an organic hydroperoxide, for example tert.butyl- or cumyl-hydroperoxide, or according to what taught in Synthesis, 1986, page 89. It is thus obtained the oxirane of formula III
  • R, Rj and R 2 are as defined above, which, treated with halide in the presence of copper(I) iodide, prepared according to what described in Organocopper Reagents: a practical approach, page 39, ed. R.I.K Taylor, provides the triol of formula IV
  • R, R R 2 and R 3 are as defined above.
  • the triol of formula TV is treated with a sulfonic acid chloride, such as, for example methan- sulfonyl-chloride or tosyl chloride, or with a halogenating agent such as, for example, phosphorous tribromide, thionyl chloride or phosphorous pentachloride and, sequentially, with a strong base, for example NaOH, to give the compound of formula V - 3 -
  • a sulfonic acid chloride such as, for example methan- sulfonyl-chloride or tosyl chloride
  • a halogenating agent such as, for example, phosphorous tribromide, thionyl chloride or phosphorous pentachloride
  • a strong base for example NaOH
  • Rj, R 2 and R 3 are as defined above, and Lg is halogen or a OS0 2 R IV group wherein R IV is a (C ⁇ )alkyl or an optionally methyl-substituted phenyl group, which subdued to a reac tion for substituting the leaving group Lg according to known methods gives the compound of formula VI
  • a suspension of copper(I) iodide (2.75 g; 14.45 mmoles) in dry THF (360 ml) and cooled to -10°C was added with a solution of 3M methyl-magnesium chloride in THF (48.2 ml; 144.5 mmoles) then dropwise added, in about 1 hour, with a solution of (E)-(2R,3R)-2-(2,4-dichlo- rophenyl)-2,3-dihydroxymethyl-oxirane obtained as described in example 1 or 2 (6 g; 24.1 mmoles) keeping the temperature at -10°C. The temperature was left to raise up to +5°C and it was stirred for 120 hours.
